How do we know that Christ died for sinners?

Romans 5:8 asserts that while we were yet sinners, Christ died for us, emphasizing that His sacrifice was intentional and directed towards those who are not deserving of grace. This doctrine of substitutionary atonement illustrates that Jesus bore the penalty for sin, making it possible for sinners to be justified before a holy God. His death on the cross is not merely historical but formatively central to the gospel, highlighting that the remedy for sin lies solely in Christ’s redemptive work, thus ensuring salvation for those whom He came to save.
